Welcome to the GERD forum! You're definitely in the right place. I had my Nissen in February 2009, and yes I did have that LOUD across the room gurgling and dumping issue during my recovery. When I went back to work, there were times people would offer me something to eat, thinking that that grumbling meant an empty stomach.
It was strange...There were times when it didn't happen, and other times, I'd eat something and he gurgling would start, and I'd know what was going to happen next.
I called it a "potpourri of poo"...quite a variety, depending on how my stomach was behaving.
The longer into my recovery, the fewer episodes I'd have...there were longer stretches when I didn't have the problem, then all of a sudden that gurgling would start up, and watch out!
I can tell you this. Sometime during the second year I suddenly became aware that I hadn't had a dumping issue for a LONG TIME. From that point on it hasn't happened again.
So, hang in there...with continued healing it will settle down. It does take time, though. I know that the gurgling can be very embarassing, and there's no way to control it...it's just something you'll have to deal with until more healing occurs and your stomach becomes adjusted to its new formation.
I used to think that it happened when I ate something more rough or irritating to my wrap...like raw veggies and salad for instance. I do think there was a connection. Who knows...I can just tell you that EVENTUALLY it will go away.
Keep the faith!
